Hi All,
My system: Windows NT 5.0 build 2195 / Apache/1.3.23 - PHP 4.1.1
Here is a nice snippet: ___________________________________________________________________________ <? function test() { $GLOBALS['test'] = 1; $test = 2; }
test(); echo $test; ?> __________________________________________________________________________
the result: 1 (however, I expected to see "2")
If I change to: <? function test() { global $test; $GLOBALS['test'] = 1; $test = 2; }
test(); echo $test; ?> ___________________________________________________________________________
the result: 2
I understand the concept o local and global variables, but isn't $GLOBALS supposed to work as an alternative to "global" statement ?
Not exactly. It allows to you access variables in the global context, but it doesn't make the variable itself global; only the 'global' declaration does that.
